We present a new estimate of the local dark matter density by
combining an updated observational determination of the stellar and
remnant mass density with an updated baryonic model and the Galactic
rotation curve.The stellar mass density is derived from the Gaia Catalogue of Nearby

We present the electrical modeling and preliminary noise characterization of a multi-mode Bulk Acoustic Wave (BAW) gravitational wave detector operating in the 100 kHz–10 MHz frequency range. The detector employs piezoelectric quartz resonators read out by two-stage DC SQUID amplifiers, whose ultra-low-noise performance is essential to approach strain sensitivities at the level of ~10⁻²¹...

Next-generation Cosmic Microwave Background (CMB) experiments — the Simons Observatory (SO) and the LiteBIRD satellite — are designed to measure CMB polarisation with unprecedented precision, targeting primordial B-modes and signatures of new physics beyond the Standard Model. Achieving these goals requires exquisite control of instrumental systematic effects.

Primordial non-Gaussianity represents one of the most powerful observational probes of the physics of the early Universe. Standard bispectrum-based estimators, used to constrain primordial non-Gaussianity from CMB observations, are typically derived under the assumption of statistical isotropy, which implies a diagonal harmonic covariance matrix. However, this assumption may break down in...

The Sandage–Loeb test provides a direct and model-independent probe of cosmic expansion by measuring the temporal drift of cosmological redshifts, offering a fundamentally different observable from standard distance-based probes. In this talk, I will present the current status of the ESPRESSO redshift drift experiment, focusing on recent results from the third observational epoch of a bright z...

A major challenge in LISA data analysis lies in the incomplete characterization of instrumental noise, motivating the development of robust, noise-agnostic detection techniques. In this work, we explore the application of Topological Data Analysis (TDA) as a novel framework for identifying deterministic gravitational wave (GW) signals embedded in noisy data. Our approach leverages Time Delay...

Dynamical Dark Energy with Dark Sector Interactions: A Combined Fluid Approach to the Hubble Tension
The Dark Energy Spectroscopic Instrument (DESI) results have shown a strong
preference for a dynamical dark energy background. The discrepancy between
early- and late-time Hubble measurements, known as the Hubble tension, plagues
the concordance ΛCDM model.In this work, we...

Next-generation nano-accelerometers, featuring advanced sensor architectures and integrated front-ends, represent a leap in measuring non-gravitational perturbations like solar radiation pressure during missions to Mercury's orbit. These instruments enable unprecedented precision in spacecraft orbit determination and gravity field recovery up to high degrees, allowing refined models of...
